The present invention relates to a position control apparatus for a power board, especially for power boards that can be easily prevented by the wind is damaged or collapsed or deformed banner by lifting the banner automatically according to the wind speed It relates to a position control device of the banner.

By installing a large number of banners, advertisements, etc. can be easily delivered to the general public. Typically, a banner is installed between two power poles and two roadside trees.

However, as described above, installing the banner not only harms the appearance but also takes a lot of work time.

Thus, conventionally, a placard is installed to install a plurality of banners simply and neatly.

Of course, in order to more easily install a plurality of banners, a technology for moving each of the banners up and down by the power, such as Patent No. 417288 is developed to improve the workability and efficiency.

However, since there is no conventional technology that can prevent the banner from being torn or collapsed or damaged by the wind due to the wind, the banner can be torn by a typhoon or strong wind, and the prop is collapsed or bent. The disadvantage is that you can lose.

Thus, in the related art, it is very inconvenient for the manager who manages each banner to manually lower the banner in close proximity to the post according to a notice such as a typhoon.

The present invention has been invented to solve the conventional problems as described above, the present invention by automatically raising and lowering the banner in accordance with the wind speed, to easily prevent the banner is damaged or collapsed or deformed by wind power, In addition, an object of the present invention is to provide a position control device for a power board banner that allows an administrator to remotely raise and lower the banner over a telephone line or a leased line.

Accordingly, the present invention, in order to achieve the above object, in the position control apparatus of the power board for power boards comprising the power transfer of the banner up and down by the power of the motor installed in the power board, to move the banner up and down A wind speed sensor installed at the upper end of the motor, power notice board to detect the wind speed, a low point sensor to detect the lower position of the banner moving up and down by the motor, and a high point sensor to detect the upper position of the banner moving up and down by the motor Provided is a position control apparatus of a power board for a display board comprising a controller for controlling a motor by receiving a signal from a sensor, the wind speed sensor, a low point sensor, and a high point sensor.

Hereinafter, a description will be given of a specific embodiment of the position control device of the power board banner of the present invention.

1 and 2 is a view showing an example of a power notice board to which the position control device of the present invention is applied, the power notice board 1 of the present embodiment is a plurality of banners 11 as in the known patent number 10-427288 ) Are raised or lowered by the plurality of motors 12, respectively, and provided with a plurality of low point sensors 14 and high point sensors 15, respectively, on the upper and lower portions of the support 13 of the power cradle 1; Describe the structure you are doing.

Of course, the position control apparatus of the present invention can be applied to a power plate that is raised and lowered while folding a plurality of banners in a folding manner as one motor, such as known patent number 10-348769, and also in one of the power plate There is a power notice board that moves a plurality of banners in stages, in this case it may be provided with one low point sensor and high point sensor.

Anyway, the position control device of the power bulletin board according to the invention is installed in the upper end of the motor 12, the power notice board (1) to move the banner 11 up and down, as shown in Figures 1 and 3 Wind speed sensor 16 for detecting the low point sensor 14 for detecting the lower position of the banner 11 to move up and down by the motor 12, the banner to move up and down by the motor 12 ( A controller 17 for controlling the motor 12 by receiving a signal from the high point sensor 15, the wind speed sensor 16, the low point sensor 14, and the high point sensor 15 to detect an upper position of the sensor 11. )

For example, FIG. 3 illustrates a structure in which one banner 11 is moved up and down by one motor 12. When the motor 12 operates, the drum 18 rotated by the motor rotates, and the drum A wire 19 is wound around 18, and as the wire 19 is wound, two banner mounting members 20 installed on the wire 19 are raised or lowered, and two banner mounting members 20 are provided. ) Between the banner 11 is raised or lowered.

In order to prevent the structure shown in FIG. 3 from mutually interfering with each other, although not shown in detail, the power tray of the present embodiment is provided with drums each rotated by each motor, and wires are wound around each drum. The banner installation member is provided on the wire of the.

The low point sensor 14 detects the low point position of the banner mounting member 20 installed at both ends of the banner 11 and outputs a signal to the controller 17. The high point sensor 15 is The high point position of the banner installation member 20 installed at both ends of the banner 11 is detected to output a signal to the controller 17.

The wind speed sensor 16 may be of a structure having a blade rotated by the wind in the present embodiment, or a structure that is deformed by the wind power of the outside air in order to interlock with the generator 21 to be described later.

The controller 17 receives an electrical signal output from the wind speed sensor 16 and calculates the electrical signal to calculate wind power that may cause a banner value or a collapse of a post, which is a sent value. If large, problems such as breakage of the banner may occur, so that electricity flows to the motor 12 in the downward direction of the banner 11.

On the other hand, when the power pole (1) is installed on the road in the mountains, since the power pole (1) can be set up where the electricity can not be supplied to the wire, an electric device produced by the independent power pole (1) itself is required In addition, an independent electric device is required even when external power is not supplied due to a sudden power failure.

Therefore, in the present invention, as shown in FIGS. 3 and 4, the generator 21 which is interlocked with the wind speed sensor 16 is connected to the lower side of the wind speed sensor 16, and supplies electricity to the motor 12. The battery 22 is connected to the generator controller 23, the generator controller 23 supplies the current generated by the generator 21 to the battery 22 and senses the overcharge of the battery 22 It cuts the current flowing in the battery 22 while blocking the current flowing back from the battery 22 to the generator 21.

Furthermore, in the present invention, since the wind speed sensor 16 detects the current wind, it is only a follow-up step in time, and it is necessary to remotely control it by the administrator in order to improve this.

Therefore, in the present invention, after the administrator recognizes a notice of a typhoon or the like, in order to lower the banner at a long distance, the wired 24, which is either a telephone line or a dedicated line, is connected to the controller 17, and the controller 17 is It includes a structure for receiving the signal input from the wire 24 to control the motor 12.

Of course, it is obvious that the power notice board to which the position control device of the present invention is applied is provided with a device for manually raising and lowering a plurality of banners.

The position control apparatus of the power message board according to the present invention made as described above acts as follows.

In general, the electric signal output from the wind speed sensor 16 having the blade rotated by the wind power is smaller than the setting value corresponding to the typhoon or the strong wind even though the electric signal output from the wind speed sensor 16 is input to the controller 17. Therefore, the rising state of the banner 11 is maintained as it is.

However, when a strong wind is generated and the value calculated according to the electrical signal output from the wind speed sensor 16 is greater than the setting value, the controller 17 drives the motor 12.

Then, the plurality of banners 11 are simultaneously lowered while the motor 12 is driven, and when the banners 11 descend to the low point, the low point sensor 14 detects this and outputs an electrical signal to the controller 17. The motor 12 corresponding to the low point banner 11 is stopped, and when all the banners 11 reach the low point, the motor 12 is stopped while being detected by the corresponding low point sensor 14.

With all the banners 11 at the low point, if the wind generated around the power source board 1 maintains the low speed wind speed for a certain time, the wind speed sensor 16 transmits this low speed state to the controller 17. And the controller 17 calculates that the wind speed is a low speed for a predetermined time to drive all the motors 12.

Then, all the banners 11 are raised by the motor 12, and the controller 17 stops the motor 12 again according to the electrical signal of the high point sensor 15 which detects the high point of each banner. Accordingly, as shown in FIG. 1, all banners are neatly installed.

On the other hand, without automatically lowering or raising the banner by the wind speed sensor 16, a manager who manages the power notice board 1 needs to lower all the banners 11.

In other words, when there is a weather forecast that a typhoon or strong wind occurs, the manager does not manually descend the banner of all power notice boards 1, but when the manager sends a signal to the power notice board 1 by wire 24, the controller 17 ) Receives this signal and operates all the motors 12 to lower all the banners 11.

On the other hand, in a state where a typhoon or the like has passed through the area, the manager may send a signal to all power boards 1 by wire to cause the controller 17 to raise all the banners 11 again.

In this way, it is possible to control the falling and rising of all banners even in a remote state where a typhoon is generated.

As described above, the position control device of the power bulletin board according to the present invention detects when a typhoon or strong wind occurs and automatically descends the banner and if the strong wind does not occur for a certain period of time to detect the rise automatically banner Therefore, it is easy to prevent the banner from being torn, and also easily protects the props of the power bulletin board which are collapsed and deformed by the force, and the administrator can conveniently control the wire by the remote control.
